Charles first worked for the Pembroke family: wife Jill, husband Stan, and their three children: Lila, Douglas, and Jason.

When the show ended its run on CBS, and entered first-run syndication in 1987, the story explained that the Pembrokes sub-leased their house and moved to Seattle, and the Powells moved in instead, thereby allowing Charles to live downstairs yet again. This time, the family consisted of grandfather Walter, mother Ellen (whose husband was in the Navy and consequently could only visit his family sporadically), and her three children: Jamie, Sarah, and Adam.
